APPARATUS FOR TANNING.

Specification of Letters Patent No. 30,598, dated November 6, 1860.

T o all whom it may concern:

Be it known that I, JESSE S. IVHEAT, of IVheeIing, in the county of Ohioand State of Virginia, have invented a new and useful Improvement inTanning Apparatus; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanylng drawings, forming a part of this speci fication, in which-Figure l, represents a front View; F ig. 2, a vertical section, and Fig.3, a horizontal section of the apparatus.

Similar letters of reference, in each of the several figures, indicatecorresponding parts.

The nature of my invention consists, lst, in the relative arrangement oft-he suction pipes, force pump, supply pipes, communication pipes,escape valve exit pipes and emptying pipes, in combination withreservoirs and vats for the double purpose of effecting a completecirculation of the tanning liquid, through all the vats and allowingeither' of the vats to be shut off from the circulation going on throughthe other vats or to be emptied if desired.

In consists, 2d, in the frames in the vats in combination with twoeccentrics and connecting rods, so arranged that all of the frames mayvibrate simultaneously, or any one of them remain at rest if desired,while the others vibrate.

Io enable others, skilled in the art, to make and use my invention, Iwill proceed to describe its construction and operation.

The bark and liquor are contained in sep arate reservoirs E2, E3, Et,E5, provided with perforated false bottoms Y, so that only the pureliquid will be allowed to pass into the spaces below the false bottoms.One reservoir El, which is destined to receive the liquor from either ofthe tanning vats hereinafter to be described, has no false bottom; as noliquor' is to be prepared in this reservoir and consequently no bark isto be placed therein.

A suction pipe A, leading to a force pump C, connects with the spacesunderneath the false bottoms of the reservoirs E2, E3, E4, E5, by meansof branch pipes A1, and by another branch pipe A1, with the reservoirEl.

A supply pipe D, leads from the force .pump and connects with thebottoms of the first two of four vats X1, X2, X3, X4, by means of twobranch pipes D1, D1. The

top of vat X1, connects with the bottom of l vat X2, by means of a pipeD2, and with the bottom of vat X3, by means of a pipe F. The top of vatX2, communicates in a simi lar manner with the bottom of vat X2, bymeans of a p ipe D3, and with the bottom of vat X, by means of a pipeF1. The top of vat X2', connects with the bottom of vat X4, by means ofa pipe F2, F3. The pipe F3, leads into a valve boX R1, provided with aweighted valve T2. The exit pipe D5, leads from the valve box R1, intothe reservoirs El, E2, E3, Et, E5, by means of branch pipes D, D2, DS,D, D1. On emptying, pipe G, connects with the bottoms of all the vats bybranch pipes G1, G2, G3, G4, and leads into the reservoir El.

The pump C, is provided with an influx and efiiuX valve T, and T1, andeach one of the branch suction pipes, branch supply pipes, communicationpipes-connecting the vats with each otherbranch efflux pipes and branchemptying pipes is provided with a stop cock.

From the above, it will be seen that when the emptying cocks are allclosed and all the other cocks opened, a continuous circulation of theliquid will be obtained from the different reservoirs through all thevats by working the force pump. As soon as either of the reservoirs isfilled, the stop cock of its efflux branch pipe is to be closed, and theliquor allowed to flow into the others. By leaving open the stop cock ofthe suction branch pipe of that reservoir, the liquor will soon bepumped out of it if it should be desirable to empty it for the purposesof cleaning, repairing, &c. By shutting up the stop cock of its suctionbranch pipe, as well as that of its eiiux branch pipe, all communicationof that reservoir with the rest of the apparatus is cut off. If itshould be desirable to isolate either of the vats from the circulationof liquor going on through the vats, it is only necessary to shut thestop cocks connecting it with the other vats and the supply pipe. Thecirculation will then go on through the other vats, as before. Theliquor contained in a vat thus isolated, can be drawn off wheneverdesired, by opening the stop cock of its branch emptying pipe and thusallow the liquor to run off into reservoir E1. The hides can then betaken out of the vats and others placed therein. To admit of free acessfor this purpose, the vats are provided with man holes O, from which thecovers can be taken off when IleCeSSaI'y.

A weighted valve T2, serves'to keep the liquor constantly under acertain pressure corresponding with the weight put on.

Each of the vats contains a frame H, hung on two pivots H1, H2. Theframes serve to support the hides and are caused to vibrate so as tokeep the hides in constant motion. The pivots H1, pass through stufhngboxes and have at their outer ends leversK, K1, K2, K3, attached tothem. Two eccentrics I, I, serve to communicate a vibrating motion tothe frames H, in the following manner: The forked end of the connectingiod"'L1, of one ofthe eccentrics, straddles the pivot at the lower endof arm K, and the forked end of the other eccentric rod L, straddles thepivot at the upper end of lever K2. A rod L3, is hinged to the lower endof lever K, and its forked end straddles the pivot at the lower end ofarm K1. A rod L2, is hinged at one end to the upper end of lever K, andits other end is forked and straddles a pivot at the upper end of leverK2. In similar manner, rods L5, and L5, connect the lower ends of leversK1, K2, and K2, K3, respectively, and a rod L, similar to rod L2,connects the upper ends of levers K1, K5.

Rods Q, Q1, Q2, Q5, are suspended from the frame of the machine and areprovided with suitable hooks--as represented in Fig. 2, at Z-into whichthe forked ends of the rods L, L1, L2, L5, L4, L5, L5, may be placedwhen they are det-ached from the pivot which they straddle.

If all the levers are connected as above described, the revolutions ofthe eccentrics will impart a rocking motion to allthe levers and to theframes H. But yif it should be desired to stop the motion of one of theFrom the above description, it will be seen that a complete circulationof the tanning liquor through the reservoirs and vats and at the sametime an incessant motion of the hide frames inthe vats are obtained thehides subjected to the amount'of pressure desired, and the communicationof either of the vats or reservoirs with the other parts of theapparatus may be cut olf, and the motion of either of the hide framesmay be stopped without interfering with the circulation through theother reservoirs and vats or with the motion of the other hide frames.The vats are constructed from or lined with any metal or material thatwill not tarnish with the tanning matter used. The reservoirs areconstructed of wood, and any number of vats or reservoirs may beemployed if connected as described.

This process is not confined to bark tannage alone, but any preparationused in tanning in a liquid state such as terra japonica, oil, &c., maybe employed.

Vhat I claim as my invention and desire to secure by Letters Patent, is-

1. The relative arrangement of the suction pipes A, A1, force pump C,supply pipes D, D', communication pipes D2, D3, D4, F, F1, F2, F3, eXitpipes D5, D, D7, D2, D2, D10, and emptying pipes Gr, G1, G2, G3, Gr", incombination with reservoirs E, El, E2, E5, E4, E5, vats X1, X2, X5, Xt,and weighted valve T2, for the double purpose of eecting a completecirculation'of the tanning liquid and pressure upon the hides, throughall the vats and allowing'any of the vats to be shut off from thecirculation going on through the other vats and to be emptied ifdesired, substantially as set forth.

.2. The frames H, in the vats in combination with two eccentrics I, I,and connecting rods L, L1, L2, L5, L4, L5, so arranged that all of theframes may vibrate simultaneously, or any one of themremain at rest ifdesired,

while the others vibrate, substantially as set forth.
